Study on Drought Resistance Status of Camellia Sasanqua
Abstract: Camellia sasanqua, an evergreen shrub, belongs to Theaceae. Cold resistance of Camellia sasanqua was analyzed in several experiments; however, there is little research on drought resistance. Therefore, drought resistance of Camellia sasanqua was studied here. To understand growth, physiological and biochemical status of Camellia sasanqua palnts, the methods of physics and chemical measurement was applied here. Analysis on leaf area, dehydrating rate, relative water content, relative membrane permeability and soluble sugar content of Camellia sasanqua plants was performed to understand the effect of drought on Camellia sasanqua and the ability to adapt to the environment. The water lose experiment performed in different time and humid conditions showed that Camellia sasanqua has the ability to enhance drought resistance via adapting to the environment and self regulation. The drought resistance of Camellia sasanqua is stronger than that of Euonymus Japonicas cv.Aureo-ma and weaker than that of Horny Holly as well as Pittosporum. Hence in the aspect of drought desistance of Camellia sasanqua, it is necessary to cultivate better variety.
